Click handler in ItemRenderer on "hovered" state

Hey,
im trying to add Button to spark List itemRenderer and listen for click. If button is still there (not usin includeIn) it works.
But when it's just visible in "hovered" state, click is not dispatched. Is it bug? or can you let me know some workaround.
Thank you

Ah yeah, what Alex said...
I just built a simple example with s:List and a custom renderer and a Button control only in the hovered state and it appears that after mouse down the state changes and the button disappears before the mouseUp happens. My workaround was to show the button in both the hovered and selected states.

Programmatically selecting hovered state of item renderer - Greg pleeease

I'm a bit new to Flex, so I have the idea but can't get it to work.
I'm using an item renderer that takes its data from an HTTPService
    <s:SkinnableDataContainer
                              dataProvider="{boData}"
                              itemRenderer="extras.BoItemRenderer"
                              skinClass="extras.BoSkin" />
the boData data provider is an ArrayCollection not an Array
In my <s:ItemRenderer ...... > (BoItemRenderer.mxml) I have
- 2 states: normal and hovered (each has different style, which I will leave out to keep things simple)
- and the data is presented as follows:
    <s:HGroup>
        <s:Label text="{data.idNum}" />
        <s:Label text="{data.firstName}" />
        <s:Label text="{data.lastName}" />
    </s:HGroup>
Naturally as I hover on any row in the item renderer, it changes to the hovered state styling, all done by flex.
What I want to do however is programmatically induce that hover state without actually hovering.
For example, given a hard-coded idNum, I need to programmatically set the state of that row to hovered.
My approach is as follows, but not sure how to target that specific item,
- search the dataProvider to find the index of the row with idNum that matches my hard-coded value. I looked at the documentation, and there is indexOf, but it's for Array and not ArrayCollection.. also not sure how that works since I'd like to read the data from the item renderer directly, not from the original data provider.
- then I would find that index in the itemrenderer and set the state of that index to hovered.
Simpler said then done, but I'm stuck on it...
Thanks,
David

Depending on what is it the ArrayCollection, in theory you might be able to do this:
var myIndex:uint;
for(var a:uint=0;a<myCollection.length;a++){
    if(myCollection.getItemAt(a).idNum == myHardCodedIdNum){
        myIndex = a;
        break;
You can programmatically simulate a hover over by having the component manually dispatch a mouseOver event, but this is not the way to do it with itemRenderers.
Item renderers can be tricky, particularly if they are being used in List based controls, like List, DataGrid, TileList, etc. because the itemRenderers are recycled.
With that in mind, and with your somewhat non-typical situation (manually simulating hover over), I might be wrong on this, but it might be best to control this via the dataProvider data. So have a field named currState, and somehow make the renderer automatically change its state if that data field changes, then you simply programmatically change the currState data field for the desired item.
As far as how to change the state of the item renderer based on changes to a data field, maybe ChangeWatcher?

How to move a selected row data from one grid to another grid using button click handler in flex4

hi friends,
i am doing flex4 mxml web application,
i am struck in this concept please help some one.
i am using two seperated forms and each form having one data grid.
In first datagrid i am having 5 rows and one button(outside the data grid with lable MOVE). when i am click a row from the datagrid and click the MOVE button means that row should disable from the present datagrid and that row will go and visible in the second datagrid.
i dont want drag and drop method, i want this process only using button click handler.
how to do this?
any suggession or snippet code are welcome.
Thanks,

Click handler for a span

Hi
I have a TextFlow which contains several span elements. (Each has an ID attribute.) When the user clicks on one of these spans, a pop up should appear whe the user can style the span.
I tried to assign a different event listener to each of the spans, but failed.
This brings the same result for both spans:
     element.tlf_internal::getEventMirror().addEventListener(MouseEvent.CLICK, regionClickHandler);
    public function regionClickHandler(evt:MouseEvent):void {
       Alert.show(evt.currentTarget.name.toString());
Any ideas?
Tobi

Thanks for your reply Richard!
I have
    textFlow.interactionManager = editManager;
and no SelectionManager. (I assume only one of them can be used for a specific TextFlow instance).
It seems editManager.tlf_internal::computeSelectionIndex doesn't exist.
To all TLF implementers:
When a user clicks on a span in an editable TextFlow, my click handler should do something with that span (open a pop up containing a style editor for that span).
Is there a simple way to get the span that the user clicked on? It would be great if the event would have a method which returns that span.
Tobi

Click Handler

Hi,
this might be pretty simple, but I'm trying to find the
button component's click Handler in flash... can anyone help me
with this or help me with the action scripting for such an event...
thanks!

click handler is for component under flash MX & below,
you can find it under parameters at property inspector, or
component inspector...
in MX2004 & above, we can attach the script directly to
the component instance
on(click){
//do something
}

PDF handler issue reading Schwab brokerage statements

I cannot read my brokerage statements on my Schwab account. I can read various PDF files (on my Schwab account), but when I click on a brokerage statement, it opens up a new screen flashes for a second and reports done, but the screen is blank. No error message. A part of the link name has "PDFHandler" in it; whereas, when I choose other PDFs to view, it does not. I have Windows 7 Adobe 10 and as mentioned in other threads went into Adobe Reader and set it as the default PDF handler (it was the only thing available in the pulldown BTW). Any help would be greatly appreciated.

Many thanks for the quick response, Bill. On your hunch that the browser
might make a difference, I tried clicking on the same sites' .pdf files in
Chrome and IE, rather than my normal Firefox browser. They opened on-screen
without a problem. Looks like I may have a Java plugin problem in Firefox,
rather than an AA XI issue. Also looks like Windows Vista supports AA XI
without a problem.

How do I handle NULL returns from prepared statement?

Thanks in advance to all those who respond. As a beginner with Java/JSP/JDBC, I need all the help I can get!
Here's the problem...
I'm using a prepared statement in JSP to query a MySQL database.
If there is a value to return, everything works properly.
If the query returns a NULL (empty set) value, I get the following error:
javax.servlet.ServletException: Before start of result set
Here's the code (no negative comments please...I know I'm violating some conventions! I'll restructure it later. Right now I just need help with handling the NULL case):
<%
Driver DriverAppt = (Driver)Class.forName(MM_test_DRIVER).newInstance();
Connection ConnAppt = DriverManager.getConnection(MM_test_STRING,MM_test_USERNAME,MM_test_PASSWORD);PreparedStatement StatementAppt = ConnAppt.prepareStatement("SELECT lastname FROM appts_pid1 WHERE user_id = " + Recordset1__MMColParam + " AND year = " + yy + " AND month = '" + months[mm] + "' AND date = " + dates[dd] + " AND appttime = '16:15:00'");
ResultSet Appt = StatementAppt.executeQuery();
boolean Appt_isEmpty = !Appt.first();
boolean Appt_hasData = !Appt_isEmpty;
Object Appt_data;
int Appt_numRows = 0;
%>
Thanks for the help!!!

I think I have a better handle on what's occurring here. To cut to the heart of the problem, I'm going to give a very simple example that illustrates what type of error handling I need.
HERE'S THE EXAMPLE:
Let's say that I have a database of users. There are only two columns in the database: user_id and lastname. There are only 2 users, user_id "1" has lastname "Jones" and user_id "2" has lastname "Smith".
I built a very simple web interface that let's a user enter a number to see if there's a lastname associated with that record. The user has no way of knowing if the user_id exists or not, so they may or may not enter a valid number.
If the user enters a valid user_id (in this case "1" or "2"), then the correct lastname is displayed. If the user enters an invalid user_id (in this case, anything other than "1" or "2") then I get the same "Before start of result set" error that I'm getting in my real application.
So, the question is: WHERE IN THIS CODE WOULD I HANDLE THE RETURN OF AN EMPTY SET?
The goal here is to have the sentence say "The user's lastname is .", basically returning null. If there has to be a value, then have the last sentence say "The user's lastname is unknown."
If you can solve this simple example, you'll have also solved the problem with my main application!!!! :-)
Here's the example code:
<%@ page contentType="text/html; charset=iso-8859-1" language="java" import="java.sql.*" errorPage="" %>
<%@ include file="Connections/example.jsp" %>
<%
String Recordset1__MMColParam = "1";
if (request.getParameter("user_id") !=null) {Recordset1__MMColParam = (String)request.getParameter("user_id");}
%>
<%
Driver DriverRecordset1 = (Driver)Class.forName(MM_example_DRIVER).newInstance();
Connection ConnRecordset1 = DriverManager.getConnection(MM_example_STRING,MM_example_USERNAME,MM_example_PASSWORD);
PreparedStatement StatementRecordset1 = ConnRecordset1.prepareStatement("SELECT * FROM test_table WHERE user_id = " + Recordset1__MMColParam + "");
ResultSet Recordset1 = StatementRecordset1.executeQuery();
boolean Recordset1_isEmpty = !Recordset1.next();
boolean Recordset1_hasData = !Recordset1_isEmpty;
Object Recordset1_data;
int Recordset1_numRows = 0;
%>

How to handle special characters in SQL statements

How do you handle special charactes in a SQL statement? Here is an example:
update table
set notefield = 'This is Waldo's note'
where keyfield = 7;
Because the database connectivity vi accepts a string datatype wire, the ' in Waldo's note is seen as the end of string and an error is generated.
Is there a way to tell labview that the ' is part of the string and not the string delimiter?
Waldo

If two single quotes don't work, try backslash single quote, like \'
The backslash is often used as an escape character, meaning to treat the next character literally.

Jtree node refuses to collapse upon clicking handle; makeVisible() was used

Hello,
While creating a new node and inserting as a leaf in the JTree, I use tree.makeVisible(newTreePath) to expand the new node and make visible. (Using expandPath() will not expand if a leaf was added).
However now the jtree node refuses to collapse upon clicking the node handle.
How do I get it to not insist on staying open - be able to collapse manually?
thanks,
Anil

This is the JNI forum. I don't believe your post fits.
then
can I correctly assume that any class that
"implements Cloneable" will handle making either a
"shallow" or "deep" ... or even "semi-shallow" clone,
respective to the class context .. right?
It probably does something. The implementor might not have implemented anything though. And you have no idea what they implemented.
No idea about your other question.
You might want to think carefully about why you are cloning though.

Double Click handling with Submit Button

Does a submitButton on the page automatically handle / block the user's double click action?
I have an application where a submit button causes processing & commits to occur.
I want to make sure that when the user "double-click" the button, it doesn't cause problems.
Thanks

Hi
Does a submitButton on the page automatically handle / block the user's double click action?No it doesnot handles so..
You can write the below code in processRequest method of your controller to disable the button till the moment processing is going on,After processing completes you can again click submit button.
OAWebBean body = pageContext.getRootWebBean();
if(body instanceof OABodyBean)
((OABodyBean)body).setBlockOnEverySubmit(true);
}Please refer to this article for more details

Moreover,if you want to disable the button after first click then on click of get an event redirect it to same page and make it disabled or use Partial page rendering for this.
Thanks

Handling menu selection in multi states of states machine

Hi everyone,
My application uses states machine architecture, I have to handle menu selection in two different states and the 2nd of them has to be handled by the event case structure.
The problem is that when I use event structure in the 1st state it is also handled later by the event case in the 2nd state and it is impossible to handle menu selection in the 1st state by the "Get Menu Selection" block because according to it's descripton if event structure is configured to handle the same menu as item as this block, LabVIEW ignores this function.
I would be greatful for any clue.
Greetings,

Making a video appear by clicking a button on that same state.

I have a state that I want to open which has an image background and buttons to the side. When a user clicks on one of the buttons I want the video to appear over the graphic. Is there a way to do this?
I also need to have different movies play in that same player based on which button the user clicks on in that state. Is that possible too?

Best way is to have a separate state that's a copy of the first, just with a video player. An alternative is to do something like set the opacity on a button click to take a video player from invisible to visible.
In terms of playing different videos, just have each button set the source property on the video player. On Click > Play Action Sequence > Set Property > Source.

Flex datagrid itemRenderer with different states

Hi,
I have a datagrid with allowMultipleSelection="true" & itemRenderer as my custom component. The custom component have 2 states "NORMAL" & "EXPANDED".
Now on row selection the renderer should change its state from NORMAL to EXPANDED state. And if I am selecting multiple rows then all the selected rows should be in EXPANDED state.
As soon as the selection goes the renderer should retain its NORMAL state.
I am stuck. Please help me out.
Thanks in advance.

Use itemclick property of grid and it passes ListEvent to the method given for itemclick. use selectedindices or selectedcells property in grid to find which are selected and change the states for the renderers of selected rows. U can get the renderer for the current selected row using event.itemRenderer property. Hope this helps.
